- Claims. (01.197-133) This invention pertains to manifolding typewriters, andmore particularly to receptacles for collecting manifold material-for printing telegraph machines.

5 The principal object of the present invention is to provide a simple and inexpensive means whereby multiple copy paper ejected from a typewriter is made to accumulate automatically in a folded pack. p

A particular object of the invention is to provide areceptacle into whicl'rmanifolded printed sheets, especially zigzag folded. forms, are discharged from a' typewriter, which after issuing therefrom are caused to assume automatically their original folded forms.

To accomplish the above and other objects, a

device formed of sheet metal is provided which guides and maintains the printed copy of the paper out of contact with the incoming copy, thus preventing interference between the printed and unprinted copies. The printed copy is collected in its original folded form in a receptacle positioned on a bracket quickly detachable from the cover of the receiving'printer and provided with its front end curved and sloped to cause the printed copy which is directed from the point of discharge bya curved apronto accumulate in its original folded form.

A better understanding of be had from the following description, taken in conjunction with the accompanying drawings wherein: v

Fig. 1 is a perspective view of a printing telegraph receiving apparatus employing the device ofthe present invention;

Fig. 2 is a broken rear view of the receiving 'prin'ting apparatus illustrating 'the adjustable paper guidefor' the manifolded forms; and

- Fig. 3 is .a transverse cross sectional view of the apparatus shown in Fig. 1.

Referring to the drawings in which like characters represent like parts throughoutythe several views, the device according to the present invention is shown as appurtenant to a printing telegraph apparatus; for exampleas is shown in United States Patent No. 1,904,164 issued April 18, 1933 to S. Morton et a1. Such apparatus is housed in a cover or casing, indicated generally by numeral ll, Fig. l. Briefly, the device of the present invention comprises a sheet metal tray or receptacle i2, provided integrally therewith with a guide portion or lip I3 to bridge the gap between the discharge opening ll (Fig. 8') of the cover II and the receptacle, whereby the continuous printed form will be effectually guided the invention may from the discharge opening into the receptacle. This receptacle is removably mounted upon an angle iron frame indicated generally by numeral 15 suitably carried at the rear of the cover I i.

As disclosed in Figs. 1 and 3, themultiple copy 5 paper forms a packet I6 located to the rear of the'printing apparatus (Fig. 1) andis threaded between a plate or. apron l1 and. a bar it spaced therefrom which serves to smooth the sheets of paper as they are introduced therethrough. 10 Apron l1, Fig. 3, is provided with a reverted edge portion 23 by means of which it is secured to a cross bar 24 aflixed to the inside face of the cover or casing II. The paper is advanced along the surface of the plate l1 and thence through 5 a slot I9 in the rear of the cover I thence through a guide 2| and over platen 22, through the discharge opening M and into the receptacle l2.

, As iscommon practice, the folded forms are prolongitudinal edges of which are rolled to form 30 -a smooth surface over which the folded copy may easily pass. A rod 25 longitudinally disposed intermediately with respect to the edges of guide II is provided and so arranged as to cause a depression in the folded form between salt! edges of 35 the guide. Thus, when the folded form is drawn through the guide 2| by means of the engagement of its marginal perforations with the sprocket wheel means on the platen 22, resistance is offered to the folded form so that tautness is achieved 40 between the guide 2| and the. platen 22. A guide plate 26 is provided at the discharge opening of the casing I to guide the folded form therefrom and is adjustably mounted on the casing II so as to control the size of the discharge opening it to accommodate forms comprising various numbers of sheets of paper; that is, various plies of v material, for example, ranging from one to six sheets. It is manifest that the opening ll required for a single sheet is considerably smaller 60. than that required for six sheets, especially when folded forms are employed. Moreover, the regulation of the size of the discharge opening is conducive also to the sound-proofness of the printing apparatus. It has been found in practice that the gap between the outer edge of guide 26 and the edge of apron l3 which results when the guide 26 is adjusted to provide the smallest opening at I4 is not objectionable or detrimental to the smooth and emcient operation or performance of the device according to the present invention. Thus, the present device lends itself readily to existing printing apparatus.

As previously described, the receptacle I2 is provided at its end adjacent the housing I I with a lip or apron portionl3 which guides the paper into the receptacle. This apron according to the present invention forms with the bottom edge of the receptacle adjacent thereto reverse curves, more particularly conformed substantially to an S-shape, to effectuate the collection of the zigzag form strips. It is essential to accomplish the spirit of the invention that the apron l3 be elevated to a point sufficiently above the discharge opening I4, and the bottom of the receptacle be located sufficiently below said opening to permit the folded form to be properly refolded.

Thus, as the forward end of the folded form is emitted from the printing machine it travels up the incline plane formed by apron or lip I 3 and thence over the curved portion of the lip and downwardly into the receptacle l2 where the operator (unless the first fold or crease to approach the receptacle is re-entrant', that is, pointed downwardly, in which event the folding will be initiated automatically) will adjust the first fold so that it will lie flat on the bottom of the receptacle after which the folding will proceed automatically. The subsequent folding is effected so that the re-entrant angles of the folded form with respect to the apron portion I3 and the receptacle will be vertically aligned at the right end of the receptacle, that is nearest the printer, as viewed in Fig. 3, and the saliently or upwardly disposed creases of the folded form with respect to the apron I! will vertically align at the opposite end of the receptacle. Hence, as the folded form is advanced continuously into the tray or receptacle the re-entrant angled crease of the folded form will repose at the right hand end of the tray (as viewed in Fig. 3) and thereupon the intervening web between said re-entrant angled crease orfold and the succeeding salient angle fold will assume the flat position of the packet generally, whereupon the salient angled fold or crease will repose at the left hand end of the tray, 7

and as the folded form continues to be fed the web intervening said salient angled fold and the ensuing re-entrant angled fold will gradually, as the folded form is fed into the tray, fall from the somewhat taut position between the left hand end of the tray and the crown or apex of apron l3 to the flat position generally assumed by the packet. Then, when the ensuing re-entrant angled fold aligns with the right hand end of the packet (as viewed in Fig. 3) the cycle thus described will be repeated.

The receptacle I2 is removably mounted upon a holding frame i5, as previously noted, which frame comprises an angle-iron receiving portion 21 held by a pair of angle-iron bracket members 28 and a supporting strap 29. The ends of the member 21 adjacent the casing l I are provided with depending'portions II which are in turn provided with open ended slots adapted to fit over individual studs 32. The lower end of the brackets 28 are provided with rubber buffers 33 to prevent marring the finish of the cover N. This construction of frame I! renders it, too, readily removable.

As shown in Fig. 2, the guide plate I! is provided with fixed guide posts 34 and 35 and adjustable guide posts 36 and 31. Posts 36 and 31 are adjustable in slots 38 and 39 respectively, and permit the adjustment of the guides to accommodate paper of different widths.

Although the present invention is described in connection with printing telegraph receiving apparatus, it is understood that its use is also contemplated in other and varied forms, and that such application is limited only by the scope of the appended claims.
